BEARING FOR ROTARY SHAFTS.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed August 8, 1906. Serial No. 329,664.

To a, 11/71/0717, if; In/cs1 concern.-

Be it known that I, .Fnnnninok OGDEN, a subject of the King of Great Britain, and a resident of 1 Castle road, Keighley, in the county of York, England, have invented a certain new and useful Improvement in Bearings for Rotary Shafts, of which the following description, together with the accompanying sheets of drawings, is a specification.

This invention relates to bearings for the rotary shafts of machines known as cottongins, wherein the shafts revolve at a coinparatively high rate of speed; and my said invention consists in constructing the caps and parts in connection therewith used as portions of said bearings, whereby said rotary shafts may be better lubricated than heretofore, while the fixing in position. of such caps and parts in connection with one of the shafts therein does not require any alteration in the formatioi'i of the bearings which support said shafts.

In the accompan ing sheets of drawings, which are illustrative of my said invi-zntion, Figures 1 and 2 side and end elevations, respectively, of my improved parts shown as applied to the iiearing for one of the principal shafts of a co'tti'iii-gin. Figs. 3 and 4 are side sectional. and section end elevations, respectively, of my said improved parts. a view thereof as seen from above. Fi s. 6, 7, and S are side elevation, end elevatii plan, respectively, of the cap or holder hereinafter described. Figs. 9, l0, and 11 are side, end, and top vie respectively, of the skeleton hush hereinafter referred to.

As is well known, in connection with the bearings (L used in the machine above referred to a cotter is inserted through an opening i) in the usual way to keep the cap as heretofore constructed in position, such cap being made to allow oil or seiniliquid lubricant to pass down through it onto the shaft 0. On account of this class of machine being used in countries where the atmosphere is very warm, it is found that the lubricant as heretofore employed flows away and leaves the shaft dry and otherwise unprepared for revolving smoothly. To avoid this, I construct the cap (I so that it may have an open ing or cavity (Z for the reception of a plastic lubricant, and I make this cap (1 of such a shape that it will hold the skeleton bush f in big. e is contact with the rotary shaft 0, and the for ii'iation of this bush f is such as will enable the plastic lubricant 9 to fall into contact with the shaft 0, while its outer ends f are strong enough to act as a bearing for the shaft in a vertical direction. Over this hollow cap (Z I arrange a cover it to lit loosely, so that it may be readily detached to allow the lubricant to be easily supplied to the cavity (1.

To maintain the cap I! in position, I make use of the bolts 7c, the heads is of which are at right angles to the body part, so that they will take into the openings b in the bearing a. Thus when the nuts are screwed on these bolts 71' they firmly hold the cap (Z in position, and said cap (Z prevents said bolts from leaving their positions in the openings 6.

By thus making the cap (Z, the bushy, and the bolts of the shape described and illustrated a considerable portion of the shaft- 0 within the bearing (1 is left clear for the lubricant to contact with, while all the parts may be readily fixed in position.

Such being the nature and object of my said invention, what I claim is 1. In bearings for rotary shafts of cotton-- gins, a cap formed to fit in said bearings and having cavity to receive a plastic lubiicai'it, a skeleton bush reinovably fitting within the beaniigs below the cap, and means for securing said parts in position.

i In bearings for rotary shafts of cottongins a cap formed to fit in said. bearings and having a cavity to receive a plastic lubricant, a skeleton bush to fit within the bearings and said cap and bolts having lateral projections or wings to take into openings in said bearings in ord to secure the cap and bush in position.

In bearings for rotary shafts of cotton gins a cap formed to fit in said bearings and having a cavity to receive a plastic lubricant, a skeleton bush reinovably fitting within the hearings below said cap, means for securing said cap and bush in position and a coveifor protecting same.

In testimony whereof I have affixed mysignature in presence of two witnesses.
